增粘剂Ricobond 1756HS在氢化丁腈橡胶骨架油封中的应用

研究增粘剂Ricobond 1756HS用量对氢化丁腈橡胶（HNBR）物理性能和粘合性能的影响。结果表明：随着增粘剂用量的增大，HNBR硫化胶的综合物理性能略微下降，粘合性能提高；将增粘剂应用在大型HNBR骨架油封中，可提高密封制品的粘合性能和质量稳定性，增粘剂的最佳用量为7.5份左右。;The effect of addition level of tackifier Ricobond 1756HS on the physical properties and adhesion property of hydrogenated nitrile-butadiene rubber(HNBR) was investigated.The results showed that，as the addition level of Ricobond 1756HS increased，the comprehensive physical properties of HNBR vulcanizate decreased slightly，but the adhesion property was improved.When Ricobond 1756HS was used in large HNBR framework oil seal，the adhesion and quality stability of the seal were improved，and the optimum addition level of Ricobond 1756HS was about 7.5 phr
